SPEGIFICATION forming part of Letters Patent N0. 502,295, dated August1, 1893.

Application filetl March 27. 1893.

T0 all whom it ma;y concern:

Be it known that I, WILLIAM MOKINNE HALL, a citizen cf the UniteclStaates, residi1ig ab Victoria, in the county cf Marshall a11d State ofMississippi, have inventcd a certain new, useful, and valuableImprovexnent. in Oar-Oouplers, cf which the following is a full, clear,and exact description.

My invention l:1as relation to car couplers and it consists in the novelconstruction and arrangement of its parts.

In the accompm'ying drawings:-Figure 1, is a longitudinal sectional viewcf a drawhead and link. Fig. 2, is a top view of the drawhead. Fig. 3,is an end view of the drawhead, ancl Figs. 4, 5, and 6, are details ofdiffercnt pa1ts that will be explained;hereinafter.

The object cf my invention is toprovide an automatic coupler that can beoperated without the necessity of thc operator going between the cars.

It is dcscribed as follows: It consists cf the drawhead 1, which has inits perpendicular inner sides the horizontal grooves 2, 2. In the top cfthe drawhead is cut ehe slot 3, which has at one end the enlargement 4.In tlie said slot 4, is located the post 5, the edges of thc slotentering the reccsses 6, 6, on either side cf the said post. The slidingblock 7, is provided 011 eacli longitudinal lower edge with the flanges8, 8. Said fianges rest in the grooves 2, 2. The block 7, is alsoprovided in its lower front edge with the recess 9. Said recess ispreferably V-shaped as shown in Fig. 4. The post 5, is placed in theslot 3, by passing through the enlargcment 4; thcn the plate 10, issccured over the said enla1gement and tl1e said post is therebyprevented fro1n coming ont.- After the sliding block 7, is placed in thedrawheacl the pegs 11, are securedin the grooveS 2, 2, in front cf thesaid block and thereby the said block is prevented frorn coming out.

In connection with this couplcr a link 12,

sm1 No. 467,762. (N0 model.l

with beveled and converging ends is preferably 1ised, Said link consistscf a solid piece of iron having at each end a perforation 13.

My invention operates as f0llows :The post 5, is pullecl forward whichpnshes the sliding block 7, under tl1e pin perforation 14, in the top ofthe drawhead. Then the link is securcd in the clrawhead of thebackingcar and the free end will strike, the inclined surface 15, of thestationary drawhead. The link then passes up and strikes in the recess9, of the sliding block which pushes the said block and post 5, back,and at the same filme the pin falls 011 the said link, and as the carspull apart the pin falls through the perforation 13, in the said link.Then the lower end of the pin falls into the socket 16, in the lowerpart of the drawhead, and tl1e cars are coupled.

In coupling the pin is simply raised by hand 01 by a chain attac'hed tothe top there- 6 cf and running to the top cf the car.

Having described my invention, what I claim as new, and desire to securebyLetters Patent, is-

1. A car coupler consisting cf a drawhead having in its inner andperpcndicular sides horizontal grooves, and in its top a suitable slot;a sliding block having suitable flanges adapted to rast in said grooves,and a suitable recess; a sliding post located in said slot and adapted130 push the sliding block forwar. substantially as sei; forth.

2. In a car coupler having a suitable sliding block, a drawhead having aslot'with an enlargement cut in its top; a sliding post adapt- WILLIAMMCKINNE: HALL. Witn esses:
